Your connection was interrupted

A network change was detected.
ERR_NETWORK_CHANGED

Looks fine here, that error typically means the connection on your device changed, for example if I was using WiFi and left home and it was switching to mobile data and I tried to load a page I would get that message or if I switched networks at home etc.
